I’m rather new here and for days now I am trying a quite simple loft with different guide curves. I have one big radius on an angled face that is connected to a corner where another guide curve also connects to (maybe this is the problem?).
Since I am not too experienced in CAD Programs in general, I’m not sure if it is possible to connect two or more guide curves to one and the same dot at all.
Sometimes it selects the radius and sees it as guide curve, won’t form the loft accordingly tho.
From my perspective, it just looks like failed geometry you have too many lower angles, trying to connect to the upper angles and nothing in between to offset where the lines are going. Based on the video, it looks like you have a four sided shape up top and a six sided shape down below or seven but multiple lines going to one of the corners and when you render it it looks like it’s failing because of the geometry maybe try putting a shape in the middle that offset some of those lines so that they start to space out sooner instead of going from top to bottom, they go top to middle layer and then from middle layer to bottom you can add as many guide sketch’s into your loft as you want, to make sure the geometry lines up the way you want
Sorry the late answer. Until now I could not share a .shapr file, I didn‘t have the subscription yet.
Nevertheless; I tried an even simpler shape and it still wouldn‘t work.
With the same error message „Operation failed, because resulting body wouldn‘t be valid.“
here is my explanation. lofts don’t follow lines, they travel across bodies. sweeps will fallow lines, but only one. hope my video explanation helps!!!
Your sketch geometry makes for a more complex loft which is why it does not result per your expectations.
Here’s a workaround and the result is close. I made two different lofted bodies and did a Union. Notice that I moved the resulting node from each lofted body to the corner.
Also notice my finger pointing (red dots) at 52 seconds. This highlights a slight crease or dent in an otherwise acceptable result. Does this work for you?
As you can’t have two guides on the same summit for a single loft operation, the solution is to use several times the loft tool to create partial bodies and union them.
But if you don’t have the same number of edges on the start and end surfaces, the loft tool must add additional nodes and this ultimately creates the crease or dent that Mike mentioned.
One solution is to use the same number of edges on both surface, so cutting the top surface into 2 triangles and the bottom surface into 3 triangles but use only two of them as loft surface and the third one as a guide.
